Fire Emblem: New Mystery of the Emblem is a 2010 tactical role-playing game developed by Intelligent Systems and published by Nintendo for the Nintendo DS. Released in Japan only in July 2010, It is the twelfth entry in the Fire Emblem series, and a remake of the Super Famicom title Fire Emblem: Mystery of the Emblem. The story is based on the original content from Mystery of the Emblem, while including a customizable Avatar as the main character alongside Marth, the protagonist of Shadow Dragon and the Blade of Light. New Mystery of the Emblem also adapts the story content from the Satellaview title BS Fire Emblem into four additional story episodes dubbed the "New Archanea Chronicles".
Preparations for New Mystery of the Emblem began during development of the 2008 DS remake of Shadow Dragon and the Blade of Light. Instead of building on Shadow Dragon for New Mystery of the Emblem, the staff started over and used the original Mystery of the Emblem as their starting point. Staff included producer Tohru Narihiro, co-director and writer Kouhei Maeda, co-director Masayuki Horikawa, and character designer Daisuke Izuka. Two of the major new elements were the customizable Avatar character and the "Casual Mode", in which units defeated in missions are revived: the latter element was a point of fierce contention between staff due to the series' long-standing tradition of permanent death for characters. It is the last Fire Emblem game to remain exclusive to Japan, as the next installment, Fire Emblem Awakening, would lead to a surge in popularity of the series worldwide and led to international releases of future games. Upon release, it received generally positive reviews and went on to sell over 274,000 units.
